General Mach Discussion / Re: Mach3 m1076.m1s problem

Hi Rich

True, not enough info at the start. But consider the poor novice who doesn't even KNOW what info is needed.
(I am sure I was like that at the start too.)

Cheers

It sticks in my mind that the mS option in Mach3 does not work. I can specify 0.25 and get just that, in seconds.
How that interacts with UC100, I do not know.

Blimey! That IS a new one on me!
Oh well ... onwards. Much pride in solving the problem.

Now that I do not know. Sorry.
Can you play with it via an editor? Save current XML, edit happily (or evilly), restore XML.

Hum ...
You start at X9.95, which i assume is an undersize M10.
You have a pitch of 0.75
But you specify an end diameter of 9.00. That's effectively a thread depth of 0.95 mm, for a pitch of 0.75, or an overshoot of 0.2 mm. That's rather a lot. I might go for an overshoot of 0.075, or less.
All the same, it should still work.
I will add that i have done a LOT of theading under .062 with an ESS, and I don't think I have ever had anything like that happen.

That it is RANDOM in occurance ... - um. That is a worry!

I dunno. Have you tried staying with g94 and not changing feed rate modes? I have no idea why that should affect the X movement though (unless you are hitting deep Mach3 bugs).

Check pin assignments. You probably have the index signal wrongly assigned. It should work.

a good BOB is really worth its weight in gold, some if not most have LED's on the outputs.
Indeed!

General Mach Discussion / Re: 1000 subrutines Limit ?

« on: June 22, 2016, 12:57:30 AM »

Basically, yes, there is a limit.
Mach3 cannot handle a huge number of nested subroutines. It starts to lose variables. You have to keep the number of SRs down. Sad, but so.

Mach3 has bugs, we know Mach3 has bugs, therefore we have no cause for complaint
with huge apologies to Scott of the Antarctic.

This happened after a crash? It sometimes seems to me that Mach3 corrupts its XML file during a crash.
Go to the Diagnostics page and look under Threading. There is a default value there for Taper, which is used if you do not specify what taper you want.
'But I do specify what taper I want!"
Yeah, but does Mach3 read YOUR taper value at the start, or does it read the default value? In some cases, the value you have specified is only read LATER. I am not saying this is happening here, only that it is worth checking.

If the Taper value on that page is non-zero, set it to 0 and Save Config immediately.

If you persist in thinking of moving the table wrt to the world, you will contiinue to have problems. It is 'wrong thinking'.

Axes and directions in the CNC world are for the movement of the 'controlled point' (or tip of the milling cutter) wrt the job. This may not be intuitive at first, especially if you have been doing it the wrong way for some time, but it IS the convention which machines, CAD and CAM use. Get used to it.
